A firm has a three divisions, Division 1, Division 2, and Division 3. Divisions 1 and 2 represent 39% and 35% of the firm's value, respectively. The firm's WACC is 9.7%, Division 1's WACC is 10.6%, and Division 2's WACC is 6.9%. Neither the divisions, nor the firm as a whole have any debt or preferred stock (i.e.: their capital structures are pure equity). If the risk free rate is 3.6%, and the Market Risk Premium is 5.4%, what is the WACC of Division 3? Enter your answer as a percentage, without the percent '%' sign, and rounded to 1 decimal.
